At the beginning, I can’t say I liked it. Open source gives everyone the chance to look at the source code, and it becomes easier to spot errors for a third party, and hence report to the producer. Then there was problems with the size of the cover generated in their own webtoolsetc. In other words, I continued writing on the tutorial, and today it is much larger and contains much more information, to say the least.
